<p><tt class="literal"><span class="pre"><a href="./limit-unrolling.html" class="identifier">BOOST_MPL_LIMIT_UNROLLING</a></span></tt> is an overridable configuration macro regulating
the unrolling depth of the library's iteration algorithms. In this implementation
of the library, <tt class="literal"><span class="pre"><a href="./limit-unrolling.html" class="identifier">BOOST_MPL_LIMIT_UNROLLING</a></span></tt> has a default value of 4. To
override the default, define <tt class="literal"><span class="pre"><a href="./limit-unrolling.html" class="identifier">BOOST_MPL_LIMIT_UNROLLING</a></span></tt> to the desired
value before including any library header.
[<em>Note:</em> Overriding will take effect
<em>only</em> if the library is configured not to use <a class="reference internal" href="./cfg-no-preprocessed-headers.html#boost-mpl-cfg-no-preprocessed">preprocessed headers</a>. See
<a class="reference internal" href="./cfg-no-preprocessed-headers.html">BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS</a> for more information. — <em>end note</em>]</p>
